京6B車用油品地方標準發布 12月1日起實施
易車訊 日前，我們從相關渠道獲悉，經市政府批準，市生態環境局、市市場監督管理局聯合發布了《車用汽油環保技術要求》和《車用柴油環保技術要求》兩項強制性地方標準（以下簡稱“京6B”油品標準）。“京6B”油品標準將於2021年12月1日起實施。
原文如下：
根據中國汽車技術研究中心提供的實車試驗數據，預計使用“京6B”油品後,?汽油車顆粒物排放可下降20-30%，碳氫化合物下降10-15%，壹氧化碳下降6-10%。柴油車顆粒物排放可下降20%，氮氧化物下降10%。將為改善空氣質量、實現細顆粒物（PM2.5）和臭氧協同減排發揮重要作用。
移動源排放汙染是北京市大氣中PM2.5的最主要來源之壹，占本地排放比例的45%。截至2021年6月，全市機動車保有量達670余萬輛。為治理移動源汙染，北京市圍繞“車、油、路”等環節，多措並舉。在車用油品方面，先後在2004年、2005年、2008年、2012年和2017年，分別實施了“京2”、“京3”、“京4”、“京5”和“京6”車用油品地方標準，取得了較好減排效果。國際經驗也表明，車用油品升級可大幅削減車輛汙染排放。
相比現行的“京6”油品標準，“京6B”油品標準進壹步加嚴了汽油烯烴、芳烴和餾程限值，以及柴油多環芳烴、餾程限值，並新增了部分有害物質限值。
汽油方面：
加嚴烯烴含量限值。降低烯烴含量將會減少膠質的形成，從而減少發動機積碳，有利於減少碳氫化合物和顆粒物排放。
加嚴芳烴含量限值。降低芳烴含量將會減少發動機進氣系統和燃燒室積碳，有利於減少碳氫化合物和壹氧化碳排放。
加嚴汽油餾程50%蒸發溫度、90%蒸發溫度和終餾點限值。降低餾程可顯著減少汽油中重質組分含量，改善車輛燃燒性能，有利於減少碳氫化合物、壹氧化碳和顆粒物排放。 增加了氯、矽等物質的含量限值，有利於杜絕有害物質添加。
柴油方面：
加嚴多環芳烴含量限值。降低多環芳烴含量可顯著減少顆粒物生成前體物，並減少氮氧化物排放。
加嚴柴油餾程50%餾出溫度、90%餾出溫度和95%餾出溫度限值。降低餾程可減少柴油中重質組分含量，改善燃燒性能，減少顆粒物排放。
增加了“不得加入鹵素、含矽、含磷化合物等任何可導致汽車無法正常運行的添加物或汙染物”的要求，有利於杜絕有害物質添加。<!--5f39ae17-8c62-4a45-bc43-b32064c9388a:[{"blockId":"8372-1625737442687","blockType":"paragraph","styles":{"align":"left","text-indent":0,"indent":0,"line-height":1.75,"back-color":"","padding":""},"type":"paragraph","richText":{"data":[{"char":"　"},{"char":"7"},{"char":"月"},{"char":"7"},{"char":"日"},{"char":"，"},{"char":"经"},{"char":"市"},{"char":"政"},{"char":"府"},{"char":"批"},{"char":"准"},{"char":"，"},{"char":"市"},{"char":"生"},{"char":"态"},{"char":"环"},{"char":"境"},{"char":"局"},{"char":"、"},{"char":"市"},{"char":"市"},{"char":"场"},{"char":"监"},{"char":"督"},{"char":"管"},{"char":"理"},{"char":"局"},{"char":"联"},{"char":"合"},{"char":"发"},{"char":"布"},{"char":"了"},{"char":"《"},{"char":"车"},{"char":"用"},{"char":"汽"},{"char":"油"},{"char":"环"},{"char":"保"},{"char":"技"},{"char":"术"},{"char":"要"},{"char":"求"},{"char":"》"},{"char":"和"},{"char":"《"},{"char":"车"},{"char":"用"},{"char":"柴"},{"char":"油"},{"char":"环"},{"char":"保"},{"char":"技"},{"char":"术"},{"char":"要"},{"char":"求"},{"char":"》"},{"char":"两"},{"char":"项"},{"char":"强"},{"char":"制"},{"char":"性"},{"char":"地"},{"char":"方"},{"char":"标"},{"char":"准"},{"char":"（"},{"char":"以"},{"char":"下"},{"char":"简"},{"char":"称"},{"char":"“"},{"char":"京"},{"char":"6"},{"char":"B"},{"char":"”"},{"char":"油"},{"char":"品"},{"char":"标"},{"char":"准"},{"char":"）"},{"char":"。"},{"char":"“"},{"char":"京"},{"char":"6"},{"char":"B"},{"char":"”"},{"char":"油"},{"char":"品"},{"char":"标"},{"char":"准"},{"char":"将"},{"char":"于"},{"char":"2"},{"char":"0"},{"char":"2"},{"char":"1"},{"char":"年"},{"char":"1"},{"char":"2"},{"char":"月"},{"char":"1"},{"char":"日"},{"char":"起"},{"char":"实"},{"char":"施"},{"char":"。"}],"isRichText":true,"keepLineBreak":true}},{"blockId":"1128-1625737442919","blockType":"paragraph","styles":{"back-color":"","align":"left","line-height":1.75,"text-indent":0,"indent":0,"padding":""},"type":"paragraph","richText":{"data":[{"char":"　"},{"char":"　"},{"char":"根"},{"char":"据"},{"char":"中"},{"char":"国"},{"char":"汽"},{"char":"车"},{"char":"技"},{"char":"术"},{"char":"研"},{"char":"究"},{"char":"中"},{"char":"心"},{"char":"提"},{"char":"供"},{"char":"的"},{"char":"实"},{"char":"车"},{"char":"试"},{"char":"验"},{"char":"数"},{"char":"据"},{"char":"，"},{"char":"预"},{"char":"计"},{"char":"使"},{"char":"用"},{"char":"“"},{"char":"京"},{"char":"6"},{"char":"B"},{"char":"”"},{"char":"油"},{"char":"品"},{"char":"后"},{"char":","},{"char":" "},{"char":"汽"},{"char":"油"},{"char":"车"},{"char":"颗"},{"char":"粒"},{"char":"物"},{"char":"排"},{"char":"放"},{"char":"可"},{"char":"下"},{"char":"降"},{"char":"2"},{"char":"0"},{"char":"-"},{"char":"3"},{"char":"0"},{"char":"%"},{"char":"，"},{"char":"碳"},{"char":"氢"},{"char":"化"},{"char":"合"},{"char":"物"},{"char":"下"},{"char":"降"},{"char":"1"},{"char":"0"},{"char":"-"},{"char":"1"},{"char":"5"},{"char":"%"},{"char":"，"},{"char":"一"},{"char":"氧"},{"char":"化"},{"char":"碳"},{"char":"下"},{"char":"降"},{"char":"6"},{"char":"-"},{"char":"1"},{"char":"0"},{"char":"%"},{"char":"。"},{"char":"柴"},{"char":"油"},{"char":"车"},{"char":"颗"},{"char":"粒"},{"char":"物"},{"char":"排"},{"char":"放"},{"char":"可"},{"char":"下"},{"char":"降"},{"char":"2"},{"char":"0"},{"char":"%"},{"char":"，"},{"char":"氮"},{"char":"氧"},{"char":"化"},{"char":"物"},{"char":"下"},{"char":"降"},{"char":"1"},{"char":"0"},{"char":"%"},{"char":"。"},{"char":"将"},{"char":"为"},{"char":"改"},{"char":"善"},{"char":"空"},{"char":"气"},{"char":"质"},{"char":"量"},{"char":"、"},{"char":"实"},{"char":"现"},{"char":"细"},{"char":"颗"},{"char":"粒"},{"char":"物"},{"char":"（"},{"char":"P"},{"char":"M"},{"char":"2"},{"char":"."},{"char":"5"},{"char":"）"},{"char":"和"},{"char":"臭"},{"char":"氧"},{"char":"协"},{"char":"同"},{"char":"减"},{"char":"排"},{"char":"发"},{"char":"挥"},{"char":"重"},{"char":"要"},{"char":"作"},{"char":"用"},{"char":"。"}],"isRichText":true,"keepLineBreak":true}},{"blockId":"3796-1625737442923","blockType":"paragraph","styles":{"back-color":"","align":"left","line-height":1.75,"text-indent":0,"indent":0,"padding":""},"type":"paragraph","richText":{"data":[{"char":"　"},{"char":"　"},{"char":"移"},{"char":"动"},{"char":"源"},{"char":"排"},{"char":"放"},{"char":"污"},{"char":"染"},{"char":"是"},{"char":"北"},{"char":"京"},{"char":"市"},{"char":"大"},{"char":"气"},{"char":"中"},{"char":"P"},{"char":"M"},{"char":"2"},{"char":"."},{"char":"5"},{"char":"的"},{"char":"最"},{"char":"主"},{"char":"要"},{"char":"来"},{"char":"源"},{"char":"之"},{"char":"一"},{"char":"，"},{"char":"占"},{"char":"本"},{"char":"地"},{"char":"排"},{"char":"放"},{"char":"比"},{"char":"例"},{"char":"的"},{"char":"4"},{"char":"5"},{"char":"%"},{"char":"。"},{"char":"截"},{"char":"至"},{"char":"2"},{"char":"0"},{"char":"2"},{"char":"1"},{"char":"年"},{"char":"6"},{"char":"月"},{"char":"，"},{"char":"全"},{"char":"市"},{"char":"机"},{"char":"动"},{"char":"车"},{"char":"保"},{"char":"有"},{"char":"量"},{"char":"达"},{"char":"6"},{"char":"7"},{"char":"0"},{"char":"余"},{"char":"万"},{"char":"辆"},{"char":"。"},{"char":"为"},{"char":"治"},{"char":"理"},{"char":"移"},{"char":"动"},{"char":"源"},{"c
